| titleOfInvention | Anti-drainback/pressure-relieved filter cartridges for lubricating oil |
| abstract | Filter cartridges having annular filter elements retained within housings include a cylindrical valve support on which an annular valve is mounted. The annular valve has a valve skirt and a valve sleeve. During normal operation, the valve skirt deflects, allowing lubricating oil to flow to and through the filter element. When the filter element clogs, the valve sleeve deflects, uncovering openings through the valve support which the valve sleeve normally blocks. Lubricating oil then flows through the openings in the valve support bypassing the clogged filter. In accordance with one embodiment of the filter cartridge, the filter element, valve and valve support are held in axial abutment within the filter housing by a coil spring. In accordance with preferred embodiment of the filter cartridge, the filter element valve and valve support are retained in the filter housing by adhesive. |
